Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'грубый' in all contexts. For materials, 'сырой' or 'неочищенный' is better. 'Грубый' is closer for behaviour/language.
- Do not confuse with 'cruel' (жестокий).
Common Mistakes
- Using 'crude' to mean 'cruel'. (Incorrect: *He was crude to the animal. Correct: He was cruel to the animal.)
- Overusing for simple/primitive without the negative connotation. 'A basic hut' is neutral; 'a crude hut' implies it's poorly made.
